: Atmospheric concentrations of greenhouse gases such as carbon dioxide have risen dramatically over the past century. Most scientists agree that this has begun to result in global warming, a slow increase in average temperature worldwide. What are the possible consequences of global warming?

Click Play and view the BAR CHART tab. The temperature will go up and down every day, but try to look at the overall trend. What happens to the temperature over time?

Over time, the temperature gets lower and lower

Over time, the temperature remains the same

Over time the temperature gets higher and higher

Now set the Greenhouse gases to 100% and let the simulation run for a while. How does a maximum amount of greenhouse gas affect the temperature?

Over time, the temperature gets lower and lower

Over time, the temperature remains the same

Over time the temperature gets higher and higher

Question: How do greenhouse gases affect Earth’s climate? 1. Observe: Select the BAR CHART tab and click Play. After about 24 simulated hours, click Pause (ll). What do you notice about the heat flow into and out of Earth’s atmosphere?

The heat flow into Earth’s atmosphere gets higher as the Sun rises and sets. The heat flow out of Earth’s atmosphere gets lower.

The heat flow into Earth’s atmosphere varies as the Sun rises and sets. The heat flow out of Earth’s atmosphere remains the same.

The heat flow into Earth’s atmosphere rises the same as the Sun rises and sets. The heat flow out of Earth’s atmosphere remains the same.

The heat flow into Earth’s atmosphere lowers as the Sun rises and sets. The heat flow out of Earth’s atmosphere lowers.

Experiment: Select the BAR CHART tab, and click Play. While the simulation is playing, move the Greenhouse gases slider back and forth. What do you notice?

As the percentage of greenhouse gases decreases, the heat flow out of Earth’s atmosphere decreases. As the percentage of greenhouse gases decreases, the heat flow out of Earth’s atmosphere increases.

As the percentage of greenhouse gases decreases, the heat flow out of Earth’s atmosphere increases. As the percentage of greenhouse gases decreases, the heat flow out of Earth’s atmosphere increases.

As the percentage of greenhouse gases increases, the heat flow out of Earth’s atmosphere decreases. As the percentage of greenhouse gases decreases, the heat flow out of Earth’s atmosphere increases.

As the percentage of greenhouse gases increases, the heat flow out of Earth’s atmosphere increases. As the percentage of greenhouse gases increases, the heat flow out of Earth’s atmosphere increases.

: Click Play, and this time observe the GRAPH tab as you change the Greenhouse gases. What do you notice?

Increasing the greenhouse gases causes the purple line (Hout) to increase and the green line (T) to increase. Decreasing the greenhouse gases causes the purple line (Hout) to increase and the green line (T) to increase

Increasing the greenhouse gases causes the purple line (Hout) to increase and the green line (T) to decrease. Decreasing the greenhouse gases causes the purple line (Hout) to increase and the green line (T) to decrease
